    AbstractThis work is mainly concerned with the effect of anthropogenic activities and natural radioactivity due to the presence of highly radioactive black sand spots, factory construction, and shipping, in addition to other activities like agriculture on human beings. Forty samples were collected along Baltim–El Burullus coastal plain to detect the effect of these problems and determine the suggested solutions. The black sand of the Baltim–El Burullus coastal plain exhibits a considerable amount of economically heavy minerals, their ratio relative to the bulk composition in the investigated samples ranges from 3.18 to 10.5% with an average of 5.45%. The most important of them are magnetite, ilmenite, rutile, leucoxene, garnet, zircon and monazite. The existence of some radioactive-bearing accessory mineral deposits like zircon and monazite led to measuring the naturally occurring radionuclides 226Ra, 232Th and 40K to evaluate the excess lifetime cancer risk (ELCR). The results showed that these concentrations are 19.1 ± 9.73, 14.7 ± 9.53 and 211 ± 71.34 Bq kg−1 were lower than the corresponding reported worldwide average of 35, 45, and 412 Bq kg−1 for each radionuclide (226Ra, 232Th, and 40 K). The gamma hazard indices such as absorbed dose rate (Dair), the annual effective dose (AED), and excess lifetime cancer risk (ELCR) factor were computed in the investigated sediments and all the results were found (Dair = 26.4 nGy h−1, AED = 0.03 mSv year−1, ELCR = 0.0001) to be lower than the values suggested by the United Nations Scientific Committee on the effect of Atomic Research (59 nGy h−1, 0.07 mSv year−1 and 0.0029 for Dair, AED and ELCR, respectively). The study suggests that the black sand is safe to use in various infrastructure applications at Baltim–El Burullus coastal plain. The levels of radioactivity are not high enough to pose a risk to human health.

    AbstractWater pollution is referred to as the introduction of exotic species into an ecosystem, which poses serious difficulties for both the environment and human health. As a result, water treatment has garnered a lot of interest in recent studies, particularly for dyes removal. In an effort to synthesize new photocatalysts with the highest potential for removing pollutants, photocatalytic degradation of two types of dyes; aniline blue, and malachite green by newly synthesized Ag(I), Ni(II), and Co(II) complexes photocatalysts has been investigated here. Ag(I), Ni(II), and Co(II) ions were used to interact with the novel imine ligand, HL, which was produced by condensing 3-acetylcoumarin, and sulfadimidine, in order to make the desired complexes. Different spectroscopic methods were used to properly characterize and confirm the structures of all synthesized compounds. The ligand, HL act as anionic tetradentate through the imine group (C=N), lactone carbonyl group (C=O), sulfonamide group (SO2NH), and pyrimidine ring nitrogen. The suggested formula of the synthesized complexes were [Ag2(L)(NO3)(H2O)3], [Co2(L)Cl3(H2O)].2H2O, and [Ni2(L)Cl3(H2O)].2H2O with a tetrahedral structure, and nonelectrolyte nature. Through optical studies and XRD measurements, all investigated compounds have the semiconductor nature and nano sizes. TGA-DTG/DSC techniques were utilized to thermal behavior study as well as assess some thermodynamic and kinetic parameters for all degradation stages. The geometry of the proposed structure of all new synthesized compounds was optimized by density functional theory (DFT) calculations. The BET surface area and the porosity data align well with the excellent photocatalytic performance for [Co2(L)Cl3(H2O)].2H2O complex toward the dyes degradation.

    The main objective of this study is to mix two problematic wastes, cement kiln dust (CKD) and polystyrene waste liquified by gasoline, to produce a new lightweight cementitious material, as a green composite used in the construction industry. Various ratios of liquified polystyrene (LPS) were blended with CKD to achieve the optimum mixing ratio in the absence and presence of different additives. A significant improvement of mechanical properties (compressive strength of 2.57 MPa) and minimization of the porosity (51.3%) with reasonable water absorption (42.4%) has been detected in the mixing of 30% LPS with CKD due to filling the voids and gaps with liquified polymer. Portland cement, waste glass, and iron slag have been incorporated into CKD-30% LPS paste at different mass fractions of 0%, 5%, 10%, 15%, and 20%. However, a considerable value of compressive strength up to 2.7 MPa was reported in presence of 15% of any additive material with CKD-30% LPS matrix. This study recommends implementing a viable strategy to upcycle any of the examined wastes of the optimum ratios (15% waste glass or iron slag with 30% of LPS) together with another hazardous waste, namely cement kiln dust, to produce lightweight cementitious bricks in eco-friendly sustainable technology.

    Abstract The Egyptian black sand occurs especially along the beaches of northern part of the Nile Delta. Baltim-El Burullus coastal sediments lie between Longitudes 30° 10′ and 34° 15′E, and Latitudes 31° 10′and 31° 35′N. Sixty two samples from Baltim-El Burullus coastal plain were measured radio metrically by using Na-I detector for determination of 238U, 232Th, 226Ra eU and 40K concentrations. 238U concentration ranged from 1 to 5 ppm with 1.63 as an average, 232Th from 1 to 10 ppm with average 3.66 ppm, 226Ra (eU) from 1 to 6 with 1.92 as an average and 40K from 0.10 to 2.55 with average (0.76). The studied stream sediments could be intimated to different sources, leading to variability in contribution of the radioelements, thus the activity concentration of 40K > 232Th > 226Ra> 238U. eU / Ra eU ratios average (0.66), is lower than unity indicate the disequilibrium in the studied coastal sediments, suggesting disequilibrium with uranium migration out. The inter-element relations show the presence of U and Th in discrete minerals or their separate migration. The radiological hazard parameters, like the dose rate (D), the annual effective dose equivalent (AEDE), radium equivalent activity (Raeq), external (Hex), internal (Hin) hazard indices and gamma index (Iγ) were estimated for these sediments and compared with the permissible international limits. Nearly, all the studied samples are within the recommended permissible levels for most environmental parameters, with the exception of some samples lie out of the limits.

    A coordination polymer (SCP), [Cu2(CN)4·(Me3Sn)2·(phen)2], 1, was constructed based on phenanthroline monohydrated (phen), trimethyltin chloride, and K3[Cu(CN)4]. The SCP 1 consists of repeating units of tetrahedral Cu(N2C2) fragments connected by (Me3Sn)+ cations which create 1-D helical chains with the phen ligands arranged on both sides of the chain. The 1-D helical chains are arranged in a unique way to form two right-helical and two left-helical chains creating a rare quartet-helical 3-D network. The quartet-helical chains are arranged in a unique A⋯A⋯A fashion forming a 3-D network structure via H-bonds and π–π stacking. Mass, electronic and luminescence spectra are also investigated. The MTT assay was used to determine the in vitro antitumor effects of SCP 1 on human breast cancer cell line, MCF-7. Cell cycle analysis revealed that SCP 1 induced apoptosis in MCF-7 breast cancer cell line. Thus, the SCP 1 selectivity exhibits specific in vitro antitumor effects against human breast cancer cell line, MCF-7.

    Interaction of hexachlorocyclodiphosph(V)azanes, (I a − h ) with 5,5′ indigodisulfonic acid disodium salt (II) furnished the expected cyclodiphosph(V)azanes of the type (H 2 L 1 –H 2 L 8 ). The coordinating behavior of H 2 L 1 , where H 2 L 1 is 1,3diphenyl-2,2,4,4-tetrachloro-2,4-di1,1′-di(5,5′ indigodisulfonic acid disodium salt)cyclodiphosph(V)azane, towards the transition metal ions Mn(II), Co(II), Ni(II), Cu(II) and Fe(III) was studied. The structures of the isolated products are proposed based on elemental analyses, molar conductance, spectral analysis (IR,1H-NMR, and UV-Vis), as well as magnetic susceptibility measurements and thermogravimetric analysis (TGA). From the elemental analyses, 1:2 (ligand:metal) ratio is suggested, and the complexes are found to have the general formula [(M)2(L1)(Cl)x.n(H2O)]· zH2O where M = Mn(II) and Co(II) (x = 2, n = 6, z = 1); M = Ni(II) (x = 2, n = 6, z = 1.5); M = Cu(II) (x = 2, n = 2, z = nil); M = Fe(III) (x = 4, n = 4, z = 4) and (L1) = the deprotonated form of cyclodiphosphazane ligand. The molar conductance data show that all complexes are non-electrolytes. The spectral data and magnetic susceptibility measurements revealed that the ligand behaves as a dibasic tetradentate ligand coordinated to the metal ions through heterocyclic nitrogen and carbonyl oxygen atoms in an octahedral and square planar manner. Some ligand field parameters (Dq, B, and β), in addition to ligand field stabilization energy (LFSE), were calculated. The thermal behavior of these complexes is studied using TG technique and the different dynamic parameters are calculated applying Coats–Redfern equation. Antimicrobial activities have been studied using the agar–disc diffusion technique, and the higher antimicrobial activity has been observed for the iron (III) complex compared to the other metal complexes.

    A series of biologically active mononuclear complexes of Cu(II), Ni(II), Zn(II), and Fe(III) were prepared. The reactions of the Schiff base ligand 1-phenyl-2,3-dimethyl-4-salicylalidene pyrazole-5-one, (HL), with the previous metals in the presence of LiOH as a deprotonating agent, yielded different types of complexes. The binary complexes react with the mixed ligands 2-aminopyridine (2-ampy), 8-hydroxyquinoline (8-OHqu) and Oxalic acid (Ox) to form the mixed ligand complexes. All the binary and mixed ligand complexes have octahedral configurations. The Schiff base ligand (HL) is coordinated to the central metal as monoanionic terdentate ONO ligand. Thermal studies explored the possibility of obtaining new complexes, which can not be prepared from solutions. Five coordinate Ni(II) and Zn(II) complexes were prepared pyrolytically. Also, the binuclear Fe(III) complex was prepared through the thermal transformation of its mononuclear complex to the binuclear one. All complexes and the corresponding thermal products were isolated and their structures were elucidated by elemental analyses, conductance, IR and electronic absorption spectra, magnetic moments, 1 H NMR and TG-DSC measurements. The free ligand (HL) and its metal complexes showed higher antibacterial effects than that of some investigated antibiotics.
